In a mixing bowl, combine 1 cup of cottage cheese, 2 tablespoons of olive oil, and a large egg, whisking until smooth and creamy.

In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 tablespoon of baking powder, and ½ teaspoon of salt until well mixed.

Gradually incorporate the dry ingredients into the wet mixture, stirring gently with a spatula until just combined.

Carefully fold in 1 cup of finely chopped baby spinach and ½ cup of shredded mozzarella cheese into the dough.

Dust your hands with flour and take a portion of the dough, shaping it into a bagel-like shape approximately 3 inches in diameter.

Preheat your oven to 400°F (200°C). Once ready, place the baking sheet in the center rack and bake for 15-20 minutes.

After baking, remove the flagels from the oven and let them cool on a wire rack for about 5-10 minutes.
